| アブストラクト | Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication that occurs in the luteal phase of an induced hormonal cycle. In most cases, the symptoms are self-limited and spontaneous regression occurs. However, severe cases are typically accompanied by acute respiratory distress. The objective of the present study was to describe the clinical presentation, treatment, and outcome of pleural effusion associated with OHSS in three patients undergoing in vitro fertilization. The patients ranged in age from 27 to 33 years. The onset of symptomatic pleural effusion (bilateral in all cases) occurred, on average, 43 days (range, 27-60 days) after initiation of hormone therapy for ovulation induction. All three patients required hospitalization for massive fluid resuscitation, and two required noninvasive mechanical ventilation. Although all three patients initially underwent thoracentesis, early recurrence of symptoms and pleural effusion prompted the use of drainage with a pigtail catheter. Despite the high output from the pleural drain (mean, 1,000 mL/day in the first week) and prolonged drainage (for 9-22 days), the outcomes were excellent: all three patients were discharged from hospital. Although pleural effusion secondary to OHSS is probably underdiagnosed, the associated morbidity should not be underestimated, especially because it affects potentially pregnant patients. In this study, early diagnosis and appropriate supportive measures yielded favorable results, limiting the surgical approach to adequate pleural drainage. |
